SNOWPLOW.

Application led January 14, 1927. Serial No. 161,140.

The invention relates to a road cleaning machine and aims to providemechanically operated means for the removal of snow which is elevatedduring the progress of the machine and thrown to one slde of the path.

The invention contemplates an attachment which may be coupled to atractor and which is independently adjustable laterally for steerin andadapted to be elevated to insure a s ort turn being made when required.I

The invent1on furthermore provides means for vertically adjusting thefront end of the attachment, whereby to clear obstructions or for otherpurposes.

While the drawings illustrate a preferred embodiment of the invention,it is to be understood that in adapting the means to meet specific needsand re uirements, the d eslgn may be varied and suc other changes 1n theminor details of construction may be resorted to within the scope of theinvention as claimed, without departing from the spirit thereof.

For` a full understanding of the invention and the merits thereof,reference is to be had to the following description and the drawin shereto attached, in which,-

igure 1 is a side view of a snow plow, or road cleaning machine,embodying the invention, showing it coupled to a tractor.

Figure 5 is a vertical, transverse sectional view on the line 5-5 ofFigure 2, looking in the direction of the arrows.

Figure 6 is a plan View of the steering mechanism partly in section.

Corresponding and like arts are referred to in the following descrlptionand designated in the several views of the drawings by like referencecharacters.

The numeral 1 designates a tractor which may be of any make, the samebeing illustrated to demonstrate the application of the invention, whichis coupled thereto in a manner to admit of lateral adjustment forsteering, vertical adjustment for clearing obstructions and elevating toprovide for a short turn.

The plow, or cleaning machine comprises an elongated hollow casing,which is designed to operate in advance of the tractor to which it iscoupled, said casing receiving the snow as the plow advances andcontaining means, such as rotary beaters and fans, for positively movingthe snow therethrough and provided at its rear end with a spout fordischarging the snow, said spout havlng a swivel connection with thecasing, whereby it may be turned to discharge the snow to the right orto the left ofthe road, as may be found most advantageous.

The casing comprises a top 2, a bottom 3, sides 4, and a back 5, thelatter curving laterally, as indicated most clearly in Figure 3, to anoutlet 6 from which projects a collar` to which a spout 7 is connectedby means of a swlvel joint, whereby provision is had for turning thespout to discharge the snow u on either side of the road, as required.

he top 2 of the casing normally occupies an approximately horizontalposition. The bottom 3 of the casing inclines upwardly and rearwardlyfrom its forward end, so as to gradually elivate the snow in itsrearward movement through the casing. The sides 4 of the casing aresubstantially parallel so as not to offer any appreciable resistance tothe movement of the snow through the casing. The front end of the bottom3 approaches close to the surface of the road so as to leave as littlesnow thereon as possible. The front end of the plow, or casing, ismounted upon' caster wheels 8, the frames of which are secured upon thecrank portion 9 of a transversely disposed shaft 10, located below thecasing and mounted in side braces 11, which strengthen and reinforce thesides 4. An arm 12 secured to a projecting end of the transverse shaft10 is connected by means of a rod 13 to a lever 14 mounted upon thetractor within convenient reach of the drivers seat. Upon operating thelever 14 the transverse shaft 10 is rotated in its bearings and changesthe inclination of the crank portion 9, with the result that the forwardend of the plow or casing may be raised, or lowered, to clearobstructions, or for any other required pur ose.

T e upper ends of the braces 11 are connected by means of a cross piece15 from which an extension 16 projects vertically, as shown most clearlyin Figures 1 and 4. A

cable 17 attached to the extension 16 passes over a guide-pulley 18 uponthe tractor, thence over a guide pulley 19, and is attached to a druln2t), upon which it is adapted to be wound for elevating the forwardportion of the plow or casing to lift the same a distance to admit of ashort turn being made by swinging the attachment clear of the ground, asthe tractor is turned.

A U-shaped frame 21 has its side members secured to opposite sides ofthe casing and its rear cross member pivotally coupled to the tractor,as indicated at 22, in Figure 1, the connection being such as to admitof the lateral and vertical movelnents of the front portion of the plow.The steering of the device is effected by the means shown most clearlyin Figurel 6, the same consisting of telescoping side rods 23 and 24 anda cross bar 25, the latter being pivoted intermediate its ends, asindicated at 26, to a bracket 27 mounted upon the tractor. A rod 28connects one end of the eross bar 25 to a lever 29 mounted upon thetractor so as to be readily accessible from the drivers seat. The rods23 are loosely connected to opposite end portions of the shaft 10, andare tubular for the major portion of their length to receive the rods24. The rods are s0 proportioned and arranged that when the plow is setto travel straight ahead the front ends of the rods 24 touch the innerends of the openings formed in the rods 23, as indicated most clearly inFigure 6. When the cross bar 25 is turned, one of the rods 24 isadvanced, and the opposite rod 24 drawn rearward, as will be readilyappreciated. A reverse movement of the cross bar 25 reverses therelative position of the rods, thereby steering the device in anopposite direction, as will be readily appreciated. The steeringarrangement is sturdy and normally holds the plow in position to travelstraight ahead and is not affected by shock or jolts. A turnbuckle 30 isinterposed in the length of each of the rods 24 to admit of lengtheningor shortening the same, as may be required in adapting the plow todifferent tractors.

The bottom 3 of the casing is formed with a half-round depression 31 ashort distance in the rear of its forward end, and a rotary beater 32 isdisposed to operate therein. The beater 32 extends the entire width ofthe casing and its `upper portion projects above the plane of the bottom3 and is driven to rotate rearwardly, so as to move the snow through thecasing. A deflector 33 is located forwardly of the depression 31 to liftthe advancing snow and insure its delivery to the upper portion of thebeater. A bevel gear wheel 34 fast to a projecting end of the shaft orjournal of the beater 32 meshes with a companion bevel gear fast to thelower end of a vertical shaft 35. A rotary beater 36 is located withinthe forward portion of the casing` directly above the rotary beater 32and its blade or tooth, as shown most clearly in Figure 3 to penetratethe snow and assist in loosening the samefas well as cause it to moverearwardly through the casing. A bevel gear 37 fast to a projecting endof the shaft or journal of the beater 36 meshes with a companion bevelfear fast to the upper end of the vertical siiaft 35. A rotary beater 38is located rearwardly of the rotary beater 36 and both beaters 36 and 38are driven so that their lower portions travel rearwardly to positivelymove the snow through the casing. The projecting end of the shaft orjournal of the rotary beater 38 is provided with a sprocket Wheel 39which is connected by means of a sprocket chain 4() with a sprocketwheel 41 fast to the shaft or journal of the rotary beater 36.

A rotary fan or blower 42 is arranged to operate in a depression 43formed in the bottom 3 adjacent the back 5, and this fan effects apositive delivery of the snow through the outlet 6 and spout 7. Theshaft or journal of the fan 42 projects and is provided with sprocketwheels 44 and 45, the sprocket wheel 44 being connected by means of asprocket chain 46 with a sprocket wheel 47 fast to the shaft or journalof the rotary beater 38. A sprocket chain 49 connects the sprocket Wheel45 with a sprocket wheel 48 fast to the shaft of the motor or like partof the tractor. The fan or blower 42 is driven so that its upper portiontravels rearwardly to effect positive delivery of the snow through theoutlet 6 and spout 7. A deiector 50 slopes upwardly and rearwardly fromthe bottom 3 forwardly of the depression 43 and directs the snow to theupper portion of the fan or blower 42.

The device s coupled to a tractor by means of the frame 21 and pivotconnection 22 and the shaft or journal of the fan or blower 42 isconnected to a rotating part of the tractor by means of the drive chain49. As the tractor moves over the road the several beaters 32, 36 and 38are rotated together with the fan 42, and the snow scooped by the lowerforward portion of the bottom 3 is positively moved through the casingand discharged through the outlet 6 and spout 7 by the combined actionof the beaters and the fan 42. The device is steered by operating thelever 29 in the manner stated, and the front portion of the casing isadapted to be adjusted vcrticall by manipulating the, lever 14 which clanges the inclination of the crank portion 9 of the transverse shaft10, thereby raising or lowering the front end of the plow or part 3. Toeffect a short turn the drum 20 is rotated to wind a portion of thecable 17 thereon. thereby lifting the front ortion of the device clearof the ground so 1t may swing with the tractor as the latter is turned.
